Why should we trust Annapolis not to fritter away the proposed gas tax hike?

Years ago, politicians in Annapolis instituted a gasoline tax and dedicated the proceeds to transportation and roads infrastructure. There were even safeguards in place to ensure that the money was spent only for such projects.

But over the years the politicians flouted their own laws and the transportation fund was raided to balance the budget. The transportation system and roads suffered as a result.

Now the politicians in Annapolis are proposing a significant raise in the gas tax — and once again it's with the sole stated purpose of using the money for transportation infrastructure.

I guess this time they are making a double pinkie promise that all the money really, really will be spent on transportation projects this time.
